Water pollution priority

Various methods for the glc monitoring of EPA Consent Decree Priority PoUutants in water have been described (36) (see Regulatory agencies). The deterrnination of organic poUutants in water by glc and ms methods has also been detailed (37,38). Nonvolatile organic compounds in drinking water have been determined by hplc (39) (see Water, pollution).

In particular, the priority pollutant phenols (PPP), identified by EPA since the 1970s are widespread water pollutants that must receive the greatest attention due to their recognized toxicity. For the separation of eleven PPP, an ion-interaction reagent (HR) RP HPLC/UV method has been developed that allows limits of detection lower than 30 J,g in river waters, after LLE in dichlo-romethane and a 500-fold pre-concentration [82]. Through on-line SPE followed by both UV and electrochemical detection [83], 16 priority phenols have been determined in water samples with the LOD value for chlorophenols lower than 1 ng L [84]. LODs at ng L levels were obtained for all the PPPs in samples of river water, employing a relatively small volume of sample through an on-line SPE HPLC/MS method with an APCI source.
